Problems in running Chat Server over INTERNET (Very Urgent)

hi,

I've developed a full fledged Chat server and tested it on the intranet,

It works great, but i'm unable to get it going on the internet.

Registry is running at 5555, I'm using the following in my code

At server :

Naming.rebind("rmi://192.9.200.66:5555/server",sobj);

At client :

Naming.lookup("rmi://192.9.200.66:5555/server");

When my client is logging in, the client instance is not getting

registered at the server, am i going wrong anywhere or is there

any special care to be taken when it should be run over the

internet.

Despirately waiting 4 ur valuable suggestions,

kiran

KiranAny firewalls between your server and clients?These are likely to block the RMI protocol.What error message (if any) are you getting on the Java console?What version of Java are you using?RegardsMatthew

What about error messages on either the client or the server?

when the server is trying to contact the client i'm getting the exception NoRouteToHostException at

the server.

My network manager is telling that there is a firewall

at the server, but none of the ports are blocked.

I think if there is a firewall rmi protocol won't work cuz

rmi fits at transport layer, but the port on which i'm

running the server is'nt blocked by the firewall.

Any suggestions.

If rmi doesn't hold good over the internet, then what is the use of it,

The architecture and concept look good, but i dunno how to set up

over the internet.

I'm looking forward to the responses on my genuine problem:

As I said earlier my server has a firewall, but it isn't blocking any ports,

but my server is raising the exception NoRouteToHostException when it

is trying to communicate with the

client.
